    WTB: CPI CP2000

    They were never cream colored. Bright white, but all that cigarette smoke is not a good idea for a white radio & the 11 meter rag chewers.

    TRS Challenger 40 SSB

    They are crap! People caught on to this fact. Ever think why a radio is rare?More often than not it’s because they were overpriced junk!

    1970's Hy Gain SP-500 VS. Avanti Astroplane

    I tried the reincarnation of the AP. What a piece of junk! TVI back then. Folded 5/8 yeah right. There is no such thing! Much better choices out there.

    New SSB export radio coming soon - RCI X9

    I just worked on one yesterday. New out of the box, plugged it in and it blew a 30 amp fuse. Turns it the wiring harness was wired incorrectly! 12 gage wire is separated in 3 sections for + & - . Someone at the factory put red tubing on the negative and black on the positive 12 gauge wire at the...

    RCI 69 base

    This is why the base unit has a 5 digit frequency counter. To cover up the the instability. This radio never should have been designed with a 8 band selector. Look at the mobile version. It has a 6 digit frequency counter! But it’s not a 8 bander. It’s obvious as to why they did this. If you add...

    New Sirio 1/2 wave Gain Master

    27.2Mhz is where it is resonate at untrimmed. TYPO BY Sirio. Should have read 26.3 to 28.1 Mhz Resonate at 27.2 Mhz. There’s a chart showing how to trim it for frequency range. They also posted the wrong length. I personally had the 5/8 wave version up for 8 years. No issues until it got hit. I...

    New Sirio 1/2 wave Gain Master

    No it’s not. The comment I responded to was clearly before the specs were published.

    Rebuild the Stellar Turner +3 Microphone

    I work in a studio. With microphones that cost thousands of dollars and very high end equipment. The Silmic II caps are nothing more than snake oil. Put in a high quality Nichicon cap and there is absolutely no difference in sound quality. As for the tantalum caps you are subbing a non polar cap...

    More Idiotic Fet Amp's Can Wild or Mad.....LOL

    FQP13N10 do not work properly in a KL203. And the input match will be way off. 2.8. Not to mention the loss off power versus the original part. A lot of speculation as to what the part is. And some suggestions are ridiculous.

    RM-3 MOSFET TRANSISTOR

    This is a old post but completely wrong. If you tested a RM3 you would know that it is a mosfet it is not NPN transistor!
